Leave negative feedback but keep it brief and factual - you could say you were disappointed the seller did not honour the sale.
If the seller cancelled stating the items were damaged, they will get a defect on their selling account.
You need to find a more reliable seller.
"There are two ways to be fooled. One is to believe what isn't true; the other is to refuse to believe what is true.”
Søren Kierkegaard, Danish philosopher (1813 - 1855)
